| Abstract Scope |
The Powder Bed Fusion (PBF) process is used for the additive manufacturing (AM) of metal parts and is capable of producing a wide variety of complex and intricate components. For AlSi10Mg, thermal post-processing is crucial to achieve the full range of material properties. This work focuses on the effects of thermal post-processing on AlSi10Mg microstructural evolution. AM AlSi10Mg coupons were fabricated by PBF, then were thermally treated using a conventional approach (with a Solution Heat Treatment (SHT)), and an alternative approach adapted for AM (without a SHT). Micro-tensile specimens were cut by EDM, and ductility and tensile strength were measured. Microstructural differences are correlated to tradeoffs in mechanical properties. |
